Hi,

I will do this review again because I messed up with other series.

That's why there is a "depends on".

I would argue here that IEEE 802.15.4 is no "network option". However
I was talking once about moving it, but people don't like to move
things there around.
In my opinion there is no formal place to "have all the low-range
wireless such as Bluetooth, IEEE 802.11 (WiFi) and IEEE 802.15.4
together". If you bring all subsystems together and put them into an
own menuentry this would look different.

If nobody else complains about moving Kconfig entries here around it
looks okay for me.

The next person in a year will probably argue "but wireless do source
of wireless/mac80211 in net/Kconfig... so this is wrong".
To avoid this issue maybe we should take out the menuentry here and do
whatever wireless is doing without questioning it?
